I love these sandals so much, going to the river, going rafting, going hiking, lounging. EVERYTHING! When I put my Chacos on for the first time in spring I know its gonna be a good summer. I pulled my toe strap down though, I didn't like the big toe being wrapped up. So my sandals are basically a Z1 now, but this is all PERSONAL preference, some of my best friends love the big toe strap. Either way, SO COMFY! Another tip, is if you go in sand or silt, make sure to clean out the places where the straps go in after, because too much sand build up in those places can wear the straps. Otherwise, I cant wait for hot summer days climbing rocks, swimming and cliff jumping in Oregon rivers in my chacos!
